IMPROVEMENT IN MACHINES FOR MAKING ROPE.

Specification forming part of Letters Patent No. 98,491, dated January 4, 1870.

To all whom 'it may concern:

Be it known that we, BERNICE S. HALE and JAMES B. HALE, both of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Oordage Machinery; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyin g drawings, and to the letters of reference marked thereon.

The nature of our invention consists in a mechanical arrangement of a feed-roll device, for the purpose of spinning and twisting fibrous material in the manufacture of cord, cordage, and ropes, where it is desirable to give a slow uniform motion to feed-rolls in a plane normal to their axis, while revolving at a high velocity at right angles with the axis of the flier.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

Figure 1 represents a plan of our improved device. Fig. 2 represents a side elevation of the same. Fig. 3 represents a part horizontal and longitudinal section, enlarged. Fig. 4 represents an end view.

Similar letters in the different figures indicate corresponding parts.

In the construction of our improved device, a represents the drivin g-shaft, to which is secured the gear b, which engages with the gear d on hier c, giving motion to hier e and feedroll frame j'. The feed-roll frame f is secured at one end to iiier e. The other end is a hollow shaft, z', having its bearing in'hollow shaft j, this hollow shaft j turning in a stationary bearing. In feed-roll frame fare feed-rolls h h, which are connected to each other by spurgears m m m. Secured to one of these feedrolls h is the bevel-gear l, which revolves withl the feed-rolls h h around their axis in a v ertical longitudinal plane, and also these feedrolls h It revolving, with their frame f, in a. vertical transverse plane, the last being at right angles to the one rst mentioned, thus giving the feed-rolls h h a compound motion.

On driving-shaft a is secured gear c, which engages with gear g on one end of hollow shaft j, to which it gives motion, and to the bevel-gear lc, which is fast on the other end of hollow shaft j. The bevel-gear 7c on hollowT shaft j engages with bevel-gear l on feedroll h.

The motion of the feed-rolls h h on their axes 1s caused by the difference of velocity of the feed-roll frame f and the bevel-gear lc. The feed-roll frame f is operated by gears Z and d, and carries with it bevel-gear Z. A

The bevel-gear k is operated by the gears c and g. By varying the relative velocity of these two, (feed-roll frame f and bevel-gear k,) we obtain any desired velocity offeed-rolls h h, and thus give any number of twists to the inch required for the finest hair-line or largest rope.

The velocity of hollow shaft j, to which is A fixed the bevel-gear L, can be altered to any extent desired by varying the proportion of the gears c and g inversely.

The gears b, d, o, g, k, and l, being live running gears, enable us to give a much greater velocity to the feed-roll frame and ilier than by the old method of stationary gear.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The arrangement of the hollow shafts t' and j and bevel-gear k, when used in connection with the feed-roll frame f, substantially as described.

2. The arrangement and construction of the feed-roll frame j', with feed-rolls It h, bevelgears Z and lc, hollow shafts i and j, and gear g, when operating substantially as described.
